Ruminants such as cattle and sheep will produce waste gas in the process of digestion, and its composition is mainly methane, which will aggravate global warming. If people eat less meat, it will reduce the global livestock stock, thus reducing greenhouse gas emissions. Experts say people should eat less steak and hamburgers. If the global consumption of red meat can be reduced by 65,438+00%, the exhaust emissions of cattle and sheep will be reduced, which will help to slow down the trend of climate warming.
